Description

A kind of Multifunctional static electricity spinning equipment
Technical field
The invention belongs to electrostatic spinning field, more particularly, to one kind have shower nozzle self-cleaning, automatically sampling vary, (in situ) Electrostatic spinning apparatus that are modified, continuously preparing the functions such as multi-layer nano fiber membrane.
Background technology
With the development of national economy and science and technology, people are increasing to the demand of nano-fiber material, electrostatic Spining technology prepares 1-dimention nano fibrous material or nano-fiber film has the advantage of uniqueness as a kind of, thus extensive Research and application.Particularly after last century the eighties, with the proposition of this concept of nano material, it is right that research finds The optimization of the parameter of electrostatic spinning, can easily prepare diameter and reach the nanofiber of nanometer scale and even more evoke science Family is to the research interest of electrostatic spinning and enthusiasm.Electrostatic spinning is gradually in catalysis material, photoelectric material and device, bio-medical group Knit, play a great role in the field such as aerospace.
During electrostatic spinning, apply certain voltage in shower nozzle (anode), formed between shower nozzle and receiver board with one Individual electrostatic field, is in the electric charge of droplet in electric field or melt droplet table enriched, if the charge repulsion of droplet surface During more than or equal to its surface tension, droplet surface produces small " jet ", and " jet " is drawn in the presence of electric field force Stretch, solvent volatilizees rapidly, solidifies, be deposited on receiver board, that is, define nanofiber.Since formalas is first in 1934 Since the secondary experimental provision having applied for being prepared polymer fiber with electrostatic force, the spring after the patent such as rain related to electrostatic spinning apparatus Bamboo shoot, electrostatic spinning apparatus have obtained a lot of improvement, and form is also varied, solve a lot of problems, such as Chinese patent: Zl201210245532.2, zl 201210024657.2 etc.;United States Patent (USP) us6616435, us6656394 etc.;World patent: Wo06043968, wo2005099308 etc..
However, in electrostatic spinning, if the viscosity of precursor solution is too big, sweetening agent solution volatile (as ethanol does During solvent), it is easily caused solution in the solidification of shower nozzle end, grow one section of silk (see accompanying drawing 1) so that shower nozzle is plugged;And such as Fruit precursor solution polymer solubility is low, shower nozzle solution can be made to form drop, drip, these phenomenons all make Static Spinning Silk is difficult to, and reduces the efficiency of electrostatic spinning.Secondly, traditional electrostatic spinning apparatus typically adopt negative electrode (earthing pole) straight Connect as receiver board, receive Electrospun product, flexibility is not high, has certain limitation, such as: sampling is inconvenient, be difficult to into There is impact on electric field and then have influence on the pattern of Electrospun product: this laboratory in row modification, the thickness of receiver board sample Research find, when preparing nanofiber using common electrostatic spinning process, the sampling time of Electrospun product affects nanometer The appearance of fiber: the sampling time is long, that is, the time of spinning is oversize, and main nanofiber is thicker, much thin along with occurring Little fiber, the diameter of fiber is uneven (see accompanying drawing 2), and when the sampling time is shorter, the nanofiber of electrostatic spinning preparation is thick Thin ratio more uniform (see accompanying drawing 3), therefore, the control controlling sampling time of electrostatic spinning product pattern to nanofiber is very It is necessary.Finally, with the development of nano material, there is the research of novel nano-material of property with demand increasingly Many, the such as preparation of nano-fiber film and research, the study on the modification to nanofiber, even in-situ modified research, therefore, Exploitation one kind can (in situ) modified, continuously prepare what the electrostatic spinning apparatus of multi-layer nano fiber membrane were a need for, this has Experimental study beneficial to electrostatic spinning and practical application, have considerable application prospect.

Brief description
Fig. 1 is that in polymer solution electro-spinning process, shower nozzle long filament causes stifled phenomenon.From the figure, it can be seen that in electrostatic spinning During it may be possible to because solvent volatilizees too fast, the reason polymer concentration is too high, lead to the drop of shower nozzle to have little time to be formed Jet and condense, with the prolongation of electrostatic spinning time, the drop of condensation is slowly elongated, finally be in strip, cause shower nozzle block up Live, hamper carrying out further of electrostatic spinning.
Sem after Fig. 2 is polymer solution electrostatic spinning 10h schemes.The polymerization that electrostatic spinning obtains as we can see from the figure Substantially, the polymer fiber obtaining is not bery uniform for fiber diameter difference in size.
Sem figure after Fig. 3 certain polymer solution electrostatic spinning 1h.Compared with Fig. 2, it is observed from fig. 1 that 1h sampling obtains The no obvious difference of the nanofiber diameter size obtaining, distribution is relatively uniform.Electrostatic spinning obtained by Fig. 2 and Fig. 3 produces The same polymer solution of product obtains under identical electrospinning conditions, and the sample time in Fig. 2 is 10h, The sample time in Fig. 3 is 1h, the pattern of fiber have than larger difference it may be possible to because the electrostatic spinning time long, The Electrospun product of sample disc (is negative electrode) itself is thicker, have impact on electric-field intensity so that polymer fiber pattern occurs The change compared.
